Naama Beach sits in a sheltered cove near Kubura hamlet, at the very western tip of Yonaguni β Japan's westernmost inhabited island. Its calm, shallow water and white sand make it a beginner- and family-friendly snorkel spot, with coral patches and reef fish visible in the shallows just off the shore. Depth runs about 1-3m with 10-20m visibility, and July water temperature sits around 25-28Β°C. As of July 2026 it remains an unmanaged beach rather than an official swimming area, so visitors are expected to look out for their own safety.
Highlights
A 5-minute walk from Japan's westernmost point monument; also known as the spot for Japan's last sunset of the day
Calm, shallow bay with white sand, backed by exposed reef and rock at low tide
Coral patches and reef fish (including clownfish) visible right from the shallows
About 5 minutes from Kubura Port, 10-15 minutes from Yonaguni Airport
Occasional sightings of wild Yonaguni ponies near the shore
Good to know
SafetyThe cove itself is calm, but currents can build once you drift past it β stay within the guided or marked area and never snorkel alone.
SafetyThis is an unmanaged beach with no lifeguard and no jellyfish net, and it sits right next to the boat channel into Kubura Port, so keep clear of the vessel lane.
SafetyAt low tide the reef and rocks are exposed; bare feet risk cuts or sea-urchin spines, so wear water shoes, and watch for chilling if you stay in the water a long time.
SeasonBox jellyfish (habu kurage) are a summer risk from June through October β cover up with a rash guard or wetsuit, and rinse a sting with vinegar before seeking medical care.
SeasonAugust-September is peak typhoon season with a high chance of flight and ferry cancellations; April-June or late September-November are comparatively more reliable windows if snorkeling is the priority.
RulesDon't touch or collect coral or marine life, and use reef-safe sunscreen.
MannersDon't stand on coral. If a wild Yonaguni pony wanders near the beach, keep your distance and don't touch or feed it.
Practical info
Reachable in roughly 10-15 minutes by rental car from Yonaguni Airport, or about 5 minutes from Kubura Port; there's no entry fee or booking needed just to walk in, though guided snorkel tours (through local guesthouses or dive shops) are worth booking ahead. Confirm current hours, jellyfish-net status, and any tour pricing locally before you go.
